EMERGENCY-TIRE.

T 0 all whom it may concern Beit known that 1, CHARLES C. DABEL- STEIN,a citizen of the United States of America, residing at Detroit, in thecounty of ayne and State of Michigan, have invented certain new anduseful Improvements in Emergency-Tires, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to a supplemental tire for vehicles, and moreparticularly to an emergency tire for wheels which are supplied withpneumatic tires, and its object is to provide a device which may bequickly attached and which when detached may be folded for storage in asmall space.

A further object of the invention is to so construct such a tire that itmay be placed upon the wheel for use without necessitating the removalof the pneumatic tire, said emergency tire yieldingly supporting theload independently of said tire.

A further object of the invention is to provide a tire having certainother new and useful features hereinafter more fully described.

To these ends the invention consists in the matter hereinafter morefully described and pointed out in the appended claims, reference beinghad to the accompanying drawings, in which:

Figure 1, is a side elevation of a portion of a wheel with a pneumatictire in place thereon and showing a portion of an emer gency tireembodying the invention in place thereon. Fig. 2, is a transversevertical section of the same. Fig. 3, is a perspective detail of one ofthe supporting springs. Fig. 4, is a similar view of a companionsupporting spring; and Fig. 5, is a like view of a pair of attachinghooks.

As shown in the drawings, 1 represents a wheel rim of any desiredconstruction, and 2 is a pneumatic tire of any well known form held inplace in the usual manner upon the wheel rim.

The supplemental or emergency tire comprises a tread formed of a seriesof independ ent blocks 3 which are formed of rubber or other suitablematerial with transverse holes therein near the end thereof, the hole atone end of each block being adapted to receive a pivot pin whichcomprises two arms t and 5 formed integral at one end with supportingmembers 6. Each arm is formed semi-circular in cross section and whenone arm is placed upon the other with both extending through theopenings in the block, they form a round pivot for the block and alsofor links 7 having openings in their overlapped ends through which thearms extend. Each block is secured to the links which ongage it alongeach side, by the pivot members and by a pin or rivet 8 extendingthrough the hole at the opposite end of the block and through the links.The blocks are thus pivotally connected and firmly supported by thelinks.

The free end of each of the arms 4 and is formed with anotch 9 and theflat spring supporting member with which each arm is integrally formed,is provided with an opening 10 to receive said free end of the arm ofthe companion member. The flat portion of each supporting member is bentupwardly from the end of its arm and then outwardly and downwardly toextend radially of the wheel at each side of the wheel rim and pneumatictire thereon. When the parts are assembled, the arms 4: and 5 areinserted through the blocks and links longitudinally from opposite sideswith the arm 5 upon the flat upper side of the arm 4t and when the freeends of the arms engage the holes 10, the notches 9 will snap intoengagement with the edges of said openings and firmly hold the partsinterlocked and the links pivotally connected.

"' To detachably support the inner ends of theseveral pairs ofsupporting members 6, a pair of crossed levers 11 is provided for eachpair of supports. Each pair of levers is similar to a. pair of tongs,one of the levers 12 being formed with a slot 13 inter The opposite endsof the levers are bent into eyes 17 and cults end each lever is formedwith a lug 18 to holes l9 and securely and pivotally connect the ends ofthe lovers with the ends ol the spring members. Owing to the crossing ofthe levers 11, the greater the weight upon the tire, the closer thehooks 16 will engage the rim to hold the tire in place, but to preventthe hooks from becoming disengaged when they are not under load, a setscrew 20 is screwed into an opening 21 in. each lever into engagementwith the inner side of the rim. The curvature oi the hooks 16 issuliicient that said hooks are bound upon the rim 1 when the screws 20are tight, and with the inner ends oi? the love s connected to thesupporting membe' there is no danger of said levers becon'iingaccidentally displaced under ordinary operating condition. The loversare preferably formed of spring metal and owing to their crossedposition, they will yield readily under load to give the necessaryresiliency to the tire.

lhe members 6 are of such length that they will support at all times theblocks 3 forming the tread of the tire, at such a dis tance from the rimthat the pneumatic tire will be relieved of all load and all liabilityof injury to it should it become deflated from any cause, will beobviated. These arms or members may also be made of spring metal iffound desirable to yield under load. As the parts are detachablyconnected they may be quickly detached from the wheel and the pivotallyconnected tread blocks and their supporting arms folded into a smallspace.

Obviously changes may be made in the construction and arrangement ofparts without departing from the spirit of my invention, and I do nottherefore limit myself to the form or arrangement shown.

l-lavin g thus fully described my invention what I claim is:

1. In an emergency tire, the combination of a series of pivotalconnected tread members, supporting members attached to the sides of thetread members and extending radially inward at each. side of a tire upona wheel rim, and crossed levers detachably engaging the wheel rim andconnected to the supporting members to support the same.

2. In an emergency tire, the combination of a series of tread blocks, aseries of links at each side of said blocks, pivot members extendingthrough the links and blocks to pivot-ally connect the links and supportthe blocks, supporting members connected to the ends 01- the pivotmembers and extending inward at each side of a tire upon a wheel rim andmeans for detachably and yieldingly connecting the inner ends of thesupporting members to the wheel.

3. In an emergency tire, the combination of a series of tread blocks aseries of links at each side of said blocks having overlapped ends,supporting members having laterally extending arms projecting throughopenings in the overlapped ends of the links and through the blocks topivot-ally connect the links and support the blocks, and crossed leversadapted to detachably engage a wheel rim connected to the ends oi? thesupporting members to attachably connect the supporting members to awheel.

41-. In an emergency tire, the combination of a series of tread blocks,a series of links having overlapped ends provided with openings, aseries of supporting members arranged in pairs and formed with laterallyextending arms formed semi-circular in cross section, one arm of onemember of each pair of members being adapted to lie upon the arm of theother member of each pair and said arms being extended through theopenin s in the links and through the blocks and together forming pivotsfor said links, said supporting members being formed with flat portionsextending radially inward at each side of a tire upon a wheel, andmembers adapted to connect the inner ends of the supporting members to awheel.

5. In an emergency tire, the combination of a series of pivotallyconnected tread blocks, supporting members connected to each side of thetread blocks extending radially iuward of a tire upon a wheel rim, andcrossed levers having hooked outer ends to engage over the wheel rim andhaving laterally extending inner ends connected to the ends of thesupporting members.

6. In an emergency tire, the combination of a series of tread blocks, aseries of links secured to the sides of the blocks and having overlappedends provided with openings, supporting members having laterallyextending pivot arms extending through the openings in the ends of thelinks and formed with fiat portions to extend radially inward at eachside of a tire upon a wheel rim, a series of crossed levers pivot-allyconnected intermediate their ends and formed with hooked outer ends toengage over the rim of a wheel and means for detachably attaching theinner ends of the supporting members to the extended inner ends of thecrossed levers.

In testimony whereof I allix my signature in presence of two witnesses.
